Why and How to Use Milk is a cookbook that was released in April of 1936 and was written by the Department of Agriculture. This cookbook contains many recipes ranging from baked goods to soups to sauces. It is arranged in subsections that focus on the properties of milk rather than being arranged by food type. For example, there is a section on carbohydrates that highlights recipes focused on using milk’s sugars and lactose. This cookbook was written by the Department of Agriculture which means it could have been used as a way to promote the consumption of dairy products. This is evident in several of the paragraphs that highlight the many benefits of milk and its properties. After reading this cookbook, it is apparent that it is marketed towards young parents due to how much of it talks about dairy’s benefits for children. It also features a handful of pictures which are all of children eating food, presumably recipes from the cookbook. The book ends with a section about the importance of dairy products for infants and their development.
